Phenylalanine ammonia lyase (PAL) is a key enzyme controlling the biosynthesis of phenolic compounds in plants. PAL catalyzes ammonia elimination from L-phenylalanine in a reaction that yields cinnamic acid, a precursor of a large group of phenylpropanoid compounds. Phenylpropanoids and their derivatives play an important role in regulating plant resistance mechanisms under environmental stresses. By reducing the level of phenolic compounds, PAL inhibitors can induce changes in plant metabolism. This paper presents the current state of knowledge on the use of PAL inhibitors in plant biology, and draws attention to the possibilities of using PAL inhibitors in agriculture in the context of the witnessed climate changes which increase the frequency and intensity of some disasters such as droughts, floods and storms. By reducing the level of phenolic compounds, PAL inhibitors can induce changes in plant metabolism. This paper presents the current state of knowledge on the use of PAL inhibitors in plant biology, and draws attention to the possibilities of using PAL inhibitors in agriculture in the context of the witnessed climate changes.
苯丙氨酸解氨酶（PAL）是控制植物中酚类化合物生物合成的关键酶。PAL催化从L-苯丙氨酸中消除氨，该反应产生肉桂酸，肉桂酸是一大类苯丙烷类化合物的前体。苯丙烷类化合物及其衍生物在调节植物对环境胁迫的抗性机制中起重要作用。通过降低酚类化合物的水平，PAL抑制剂可诱导植物代谢发生变化。本文介绍了植物生物学中使用PAL抑制剂的当前知识状态，并在目睹的气候变化增加干旱、洪水和风暴等一些灾害的频率和强度的背景下，提请人们关注在农业中使用PAL抑制剂的可能性。通过降低酚类化合物的水平，PAL抑制剂可诱导植物代谢发生变化。本文介绍了植物生物学中使用PAL抑制剂的当前知识状态，并提请人们关注在目睹的气候变化背景下在农业中使用PAL抑制剂的可能性。
